[0021] The invention adopts the production process of yarn spinning, grey cloth weaving, singeing treatment, mercerizing treatment, napping treatment, surface impurity removal, cyclic soaping, drying and finalizing, the steps are continuous and the production efficiency is high. The singeing treatment step can burn off the short hair on the surface of the knitted grey cloth, so that the surface of the knitted grey cloth is smooth. The mercerizing treatment step can remove the concave-convex structure on the surface of the knitted grey cloth, so that the surface of the knitted grey cloth is flat, which plays a role of pre-cleaning. Finally, the surface impurity removal step allows the knitted flannel to pass through the surface impurity removal equipment and use the dust suction device to remove impurities on the surface of the knitted flannel, so as to achieve the cleaning of the surface of the knitted flannel. Since the active suction method is adopted to remove impurities, it can be avoided that the impurities are lifted up again and attached to the surface of the knitted flannel, and impurities are avoided to remain, thereby ensuring the thoroughness of impurity removal, and the efficiency is high, and rapid cleaning can be achieved, thereby improving the production efficiency of the knitted flannel. By cleaning the surface of the knitted flannel, it is avoided that impurities affect the dyeing effect of the knitted flannel, thereby ensuring the quality of the knitted flannel.

[0022] See also Figure 1As shown, the surface impurity removal equipment includes a workbench 1, and guide rollers 19 are rotatably connected at both ends of the workbench 1. The two guide rollers 19 are respectively arranged on the input end and the output end of the workbench 1. When the knitted flannel passes through the workbench 1, the guide rollers 19 will be pulled to make the guide rollers 19 rotate, so that the moving direction of the knitted flannel can be guided, so that the movement of the knitted flannel on the workbench 1 is easier and smoother. A frame 2 is arranged on the workbench 1, and the length direction of the frame 2 is perpendicular to the length direction of the workbench 1. A dust suction device and a driving mechanism connected with the dust suction device are arranged on the frame 2, and the driving mechanism is used to drive the dust suction device to move along the length direction of the frame 2. The dust suction device includes a dust suction disc 3 with an opening at the bottom, and a connecting pipe 4 is arranged on the top of the dust suction disc 3, and the connecting pipe 4 is connected with the inside of the dust suction disc 3.

The dust collecting disc 3 is a disk-shaped structure with a hollow interior, and the connecting pipe 4 is a curved pipe. Before use, the connecting pipe 4 needs to be connected to an external dust collecting device. The selected external dust collecting device is a vacuum cleaner with a long hose. The dust collecting pipe joint of the vacuum cleaner is connected to the connecting pipe 4. When the vacuum cleaner is started, a negative pressure can be generated inside the dust collecting disc 3, thereby generating suction. When the surface impurities are removed, the knitted flannel is driven by the winding device, so that it can pass through the workbench 1 quickly in a taut state. In this process, when the knitted flannel passes over the frame 2, the dust collecting device thereon will actively suck the impurities on the surface of the knitted flannel, thereby quickly removing the impurities attached to the surface of the knitted flannel, and the dust collecting device can be driven by the driving mechanism to move along the length direction of the frame 2, thereby moving along the width direction of the knitted flannel, realizing covered dust collection and impurity removal, ensuring the thoroughness of impurity removal, and having high efficiency, and being able to quickly clean the knitted flannel, thereby ensuring the quality of the knitted flannel.
